The HAY-WSA4 is an A4-sized CCTV warning sign designed to comply with data protection regulations and obligations regarding the release of video data as evidence. Measuring W210mm x L297mm, this data-compliant sign ensures that CCTV operators clearly state their name and contact details, rather than the installers’ advertising. The sign provides space for these details to be added, making it suitable for both commercial and residential properties to inform individuals about active CCTV surveillance.
